STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 372,519, dated November1, 1887.

Application filed May 25, 1887. Serial No. 239,356.

To all whom it may concern.-

Be it known that I, MrLns L. CLINTON, of Ithaca, in the county ofTompkins and State of New York, have invented a new and usefulImprovement in Steam-Boilers, of which the following is a specification.

This invention relates to an improvement in that class of steam-boilerswhich are composed of superposed or horizontal sections, and has for itsobject to produce a steam-boiler of this kind which is simple inconstruction, easily put together and operated, and which is economicalin the consumption of fuel.

My invention consists of the improvements which will be hereinafterfully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of three sheets, Figure 1 is avertical section of my improved steam-boiler. Figs. 2, 3, 4, and 5 arehorizontal sections in lines 2010, 0040, y 3/, and z z, Fig. 1,respectively. Fi 6 is a fragmentary vertical section in line 00 00, Fig.3, on an enlarged scale. Fig. 7 is a fragmentary vertical section inline 00 :0, Fig. 4, on an enlarged scale. Fig. Sis a vertical section ofone of the water-connections. Fig. 9 is a top plan view thereof. Fig. 10is a front elevation, partly in section, of the lower part of theboiler. Fig. 11 is avertical section of the upper portion of one of thefuel-magazines. Fig. 12 is a vertical section in line a: m, Fig. 2.

Like letters of reference refer to like parts in the several figures.

A represents the base of the boiler, which may be embedded into thefloor of the cellar of the building, my improved boiler being especiallydesigned for warming buildings.

a is a cinder-grate which rests upon the base A, and through which theline ashes pass into the base A, while the ciuders remain on the grate aand are removed through the door a, arranged in the front of the ash-pita B represents a base-ring or annular frame, which rests upon theash-pit a This ring is provided at its upper side with an annulardepression, I), which is divided into compartments 0 by radialpartitions If. Each compartment is provided in the bottom of the ringwith an opening, I)", which can be closed by a gate, Z)", pivoted to thelower side of the ring B.

(No model.)

C represents an annular grate-frame arranged within the ring 13 andprovided at its circumference with lugs c, which rest upon segmentalflanges a, formed on the inner side of the ring B, so that thegrate-frame can be swung back and forth in shaking The lat ter iscomposed of removable sections (t, resting upon the frame 0.

' E represents a watercolumn arranged in the center of the boiler andreceiving the feedwater at its lower end from a pipe, 6. The grate-frameO surrounds the lower portion of the water-column, and the latter isprovided above the grate with a horizontal flange, f, upon which issupported a metallic tubular protector, F, which surrounds thewater-column within the fire-chamber and prevcntsthe fuel from becomingchilled by contact with the water-column. This protector becomes red hotand transmits the heat to all parts of the surrounding fuel, therebymaintaining a uniform fire in all parts of the fire-chamber.

G G represent two superposed horizontal sections of the boiler whichinclose the firechamber. The section G rests upon the basering B and thesection G rests upon the section G.

H represents a section which rests upon the section G, and H representsa section which rests upon the section II.

I represents the dome, which rests upon the top section, II.

J represents the smoke box resting upon the dome I, and J represents ajacket or casing inclosing the sections.

9 represents water-pipes which connect the lower portion of thewater-column E with the lower section, G, and conduct the water to thesame.

71. represents the steam pipe through which the steam is taken from thedome I.

Krepresents water-passages formed, respectively, in the upper and lowersides of the sec tions, the passages in one section registering withthose of the adjacent section, so that these passages establishcommunications between the sections, as represented in Fig. 6. The twoadjacent sections are secured together by screw-bolts Z, which arearranged within the water-passages, the flanges of the latter beingconstructed in their inner edges with notches Z, inwhich the bolts arearranged. In securing two sections together the bolts are tight upperend of the water-column E is secured to.

the dome I by bolts on, arranged in the same manner in slots formed inthe adjacent flanges of the water-column and dome.

N represents ascending fines formed in the sections H H above the grate,and connecting at their upper ends with short horizontal passages a,formed partly in the upper section, H, and partly in the dome I. Eachpassage 12 communicates withadescending due, 0, which extends throughthe sections H H and through the lower sections, G G, and opens into oneof the compartments of the base ring B, between the partitions 1)thereof.

1? represents an ascending fine which extends through all t-he sectionsfrom the basering B to the smoke-box J. The ascending fines N anddescending fines O extend to the top of the dome L'but have their upperends closed by plugs 03 43, while the upper ends of the ascending finesP are open, so that the fiame and hot gases pass from the fire chamberupwardly through the ascending fines N, thence outwardly through thehorizontal passages n, thence downwardly through the descending flues O,thence through the compartments of the base-ring B, thence upwardlythrough the ascending fines P into the smoke' chamber J and smoke-pipe].Each compartment b of the base-ring B connects a descending fine, O,with an ascending flue, P. The inner walls of the lower sections, G G,are circular, as represented in Fig. 4, while those of the uppersections, H H, are indented, as rep-v resented in Fig. 2, to increasethe heating-surface and reduce the thickness of the water bodies in thesections. The top of the smokeboX J is provided with openings which arearranged in line with the fines and closed by plugs 9'. Upon removingthese plugs and those of the fines and opening the gates b in the basering the fines can be cleaned out and the ashes be discharged into theash-pit.

Qrepresents fuel-magazines arranged around the central watencolumn andsuspended from the top of the smoke-box.

q represents hinged covers which close the upper ends of the magazines.

q represents gasescape openings formed in the sides of the magazines inthe smoke-box, and g represents hinged valves arranged to open and closethe openings q.

g represents rods connecting the covers 1 with the valves g. Uponopening a cover, q,

the valve g is opened also, as represented in Fig. 10, thereby causingthe gas in the magazines to be drawn by the draft into the smokebox, andthence into the smoke-pipe. Upon closing the cover q,the damper g isclosed also, as represented in Fig. 1.

1" represents plates of metal supported on lugs at the lower ends of theascending fines N anddepending into the fireehamber. These plates becomered-hot and ignite the gases which enter the fines.

S represents a passage formed in the sides of the sections G G, and s isthe fire'door applied to said passage.

S represents an automaticreg11lator,of wellknown construction, providedwith a flexible diaphragm, 8 a chamber, 8 receiving steam through apipe, 8, from the dome I, and a spring, 3 surrounding a'stem, s. Thelatter is connected by a lever, 75, and rod t with the fire-door 8. Whenthe steam-pressure rises above the normal pressure,the fire-door isantomatieally opened, thereby checking the draft,and when thesteam-pressure falls below the normal the fire-door is closed.

to represents an upright hand-lever pivoted at its lower end to the baseA, and connected with the grate-frame G by a rod, u, so that the gratecan be conveniently shaken.

The central water column increases the steam-generating capacity of theboiler materially.

My improved boiler is easily constructed of cast-iron. and readily puttogether. It is also easily operated and kept in order.

I claim as my invention 1. The combination, with the horizontalboiler-sections provided with ascending fines N, descending fines O, andascending fines P, of a base-ring, B,provided with compartments 1),connecting the lower ends of the fines O and P, substantially as setforth.
